Sir I have 1967 two stroke Harley Davidson golf cart. It runs great on level ground but when I try to go up a incline hill it wants to stall and it only makes it up the hill using the choke. I changed the fuel filter but no help. Any suggestions greatly appreciated. I am a novice when it comes to mechanics
There could be a problem with the carburetor float chamber. The float may not be keeping a sufficient supply of fuel in the reservoir. You could try opening the float chamber and checking the float for leaks and also check the valve mechanism.
